Dark Chocolate and Cutting

In another topic on the forum someone made a comment about how he eats dark chocolate as a treat during his cut, specifically lindt's 90% cocoa bar. I was looking at the nutrient profiles for their bars for 80% and up, and I am noticing that especially the 90% bar has 14g of carbs, 6 coming from fiber for a 40 gram serving. Being on the anabolic diet, my one flaw is the weekend I do indulge on chocolate, as it is my only vice that I crave, so I figure if I can have a piece or two of this chocolate during the week it will ease the cravings. And I could even go to the 99% bar which has no sugar at all, and still 6g of fiber leaving just about 5 grams of carbs I have to account for. Is this legit, it seems perfectly fine, low carbs, good amount of fiber, high fat - perfect for what I am doing. Is this legit or am I just rationalizing something I should not be eating during the week?

just from my own research and searching the last half hour or so, as long as your not using it for significant calories I don't see how it would be bad or detrimental, just as a small treat once or twice a week to keep cravings limited
